These are a few images rendered with our program called
"tcp renderer". It was written for fun, but we used it
as basis for a scientific paper we had to write in
school.. Anyway, it renders julia and mandelbrot sets
in quaternion space, using a 4D camera that can be
placed and rotated freely in four (room) dimensions.
It is also capable of rendering 2D subsets, as shown
by the 2D Julia image to the right.
There's a simple homepage you can download the prog
